AUTOMATIC PUMPING MECHANISM.

SPECIFICATION forming part of Letters Patent No. 697,595, dated April 15, 1902 Application filed August 25,1900. Serial No. 27,984. (No model.)

To a/ZZ whom. it may concern.-

Beit known that I, ALFRED B. ANDERSON, a citizen of the United States, residing at New York, in the county and State of New York,

have invented certain new and useful Im-V provements in Automatic Pumping Mechani isms, of which the following is a specification.

This invention relates to automatic pumping mechanisms or apparatus; and it has for 1o its object to provide a pumping apparatus particularly designed for maintaining the supply-water in buildings by the employment of the buoyant action of the waste water which runs from the basins,tubs,&c. ,throughout the building.

My improved apparatusis installed in the basement or lower apartments of a building and operates to maintain a fresh supply of water in a storage tank or reservoir upon the roof zo or in the upper apartments of the building.

In the drawings, Figure 1 is a side elevation, partially in section, of the automatic pumping apparatus constructed according to my invention. Fig.'2 is a plan view thereof.

2 5 Fig. 3 is a transverse section of a detail of the construction, taken on the line who in Fig. 1 and looking in the direction of the arrow. Fig. 4 is a side elevation, partly in section, illustrating a modification of a portion of the 3o construction shown in Figs. 1 and 2. Fig. 5

is a plan view of said modification.

In the drawings corresponding reference 'characters denote corresponding parts in the several views. Y l

Referring to the drawings and toFigs. 1, 2, and 3 thereof, 1 designates a casing or tank, with whichV communicates pipe 2, leading from the water-fixtures of a building in connection with which the casing 1 is installed,

4o whereby the waste water or sewage from the basins, tubs, and other fixtures in the building will discharge into the casing 1. Preferably the casing 1 is installed in the basement or lower compartments of the building;

but it may be mounted exteriorly thereof, it desired.

3 designates a fresh-Water-supply tank or reservoir, which is preferably installed upon the roof or in the upper compartments of the 5o building and whichA is provided withy a standpipe or discharge-pipe 4,which supplies Water to the several basins and other fixtures of the building. The reservoir 3 is supplied by means of a feed-pipe 5 through the automatic action of the pumping apparatus hereinafter described and which embrace a pump proper, 6, of any adapted type.

In order to employ they lifting potential of the waste water which collects and rises in the casing 1, I provide a ball-iioat 7,- carried 6o within the casing by' an arm 8, pivotally supported by a shaft 9, passing through the casing at one side thereof, the arm 8 being arranged for vertical play and the casing 1 being preferably approximately sector-shaped to accommodate the arm 8 in its'play. Exteriorly of the casing 1 the shaft 9 carries a loose sprocket-wheel 10, provided upon one face with a ratchet 11, andthe shaft 9 carries at its end a pawl 12, arranged to operate the 7o sprocket 10 in one direction by means of the vratchet at such times as the water in the cas- 4 ing 1 is raising the ball-float 7. A stub-shaft 13 is secured to the side of the casing 1, adjacent the shaft 9, and carries two revoluble sprocket-wheels 14 andl, of which the latteris geared in connection with the sprocket 10 by means of a chain 16. A suitably-supported spring-pawl 17 servesto prevent counter revolution of-the ratchet 11 and sprocket 8o 10 during the downward movement of the arm 8 within the casing 1.

- To cause the discharge ot' the water from the casing 1, I provide a Siphon-tube 18,which leads at one endinto the lower part of the casing and atl the other end communicates with the sewer connection or drain-pipe, as shown at 19. i The Siphon-tube 18 is provided with a controlling-valve 20, which operates to close or open a portat one side thereof and 9o within the casing 1, and the arm 8 carries a projection 2 1, which is arranged to engage a projection 22, formed upon 'the valve 20, and operate thelatter upon the upward movement of the arm 8. Asa further means for operating the valve 20 I provide a float 23, which is connected with the valve by a chain-21 and which when the water within the casing has reached a predetermined level raises the valve and causes the initiation of the siphon roo action iu the tube 18 to elnpty the casing 1. The casing 1 is also provided with an overflow-vent 2U.

As a means for storing the energy or working potential of the buoyant action of the water rising in the casing 1 Iprovidea weight 25, which is suspended from any convenient structure, such asaceiling-beam 26, by means of a cable or rope 27 and pulley-blocks 28, about which the same is operatively passed. One end of the cable or rope 27 is secured to the uppermost pulley device 28, and the other end is fixed to a drum 29, carried by a shaft 31, revolubly carried by standards 30. The shaft 31 is provided with a fixed pinion 32. The standards 30 are arranged in convenient proximity to the pump 6.

Intermediate of the pump 6 and standards 30 I arrange a pair of standards 33, between which are centrally and pivotally swung, as at 33, a primary and secondary gear-carriage, respectively, 34 and 35, each of which consists, as clearly shown in Figs. 1 and 3, of triangular end pieces 36 and longitudinal body rods or bars 37, secured at their ends to the end pieces 36 at the corners of the latter. The gear-carriages 34 and 35 thus constructed constitute frames orcages for counter-balanceballs 38, which roll freely between the bodyrods 37 when the carriages are tilted, as hereinafter described. Each of carriages 34 and 35 is provided adjacent the end nearest the drum 29 with a bracket 39. The carriages 34 and 35 are arranged in the same vertical plane, as shown in the drawings, and the bracket 39 of the uppermost carriages 34 carries a short shaft 40, to which is Iixed a gear 41, arranged to mesh with the pinion 32 upon the shaft 31. The shaft 40 also carriesa fixed sprocket-wheel 42, which is geared in connection with a sprocket-whee143, the rotation of which serves to operate the pump 6. The bracket 39 of the lowermost carriage 35 carries a short shaft 44, to which is fixed a gear 45, arranged to mesh with the pinion 32. The shaft 44 also carries a fixed sprocket-wheel 46, which is geared in connection with the sprocket-wheel 14 by means of a sprocketchain 47, the sprocket-wheel 14 being upon the shaft 13, which is turned bythe chain 16 and sprockets 10 and 15.

The gear-carriages 34 and 35 are provided each at one end and in proximity to the path of vertical travel of the weight 25 with a projection-piece 48, arranged to be engaged, respectively, at predetermined phases of the upward-and-downward movement of the weight 25 to swing or tilt the carriages 34 and 35 and engage or disengage the gears 41 and 45 from the pinion 32. The carriages 34 and 35 are connected at an end of each byalinkrod or brace 49, whereby said carriages are operatively connected in a iiXed relative position.

The operation of my improved automatic pumping apparatus will be readily understood from the foregoing description, taken in connection with the following statement: The waste water,enterin g the easin g 1 through the pipe 2 from the basins, sinks, and other iixtures in the building in connection With which the pumping apparatus is installed, Will rise in the casing 1 and carry upwardly the float 7, which swings upwardly the arm 8 and turns the sprocket 10 by means of the ratchet 11 and pawl 12. The sprocket 10 turns the sprocket 15, and the sprocket 15 turns the sprocket 46 and gear 45, which latter, with the parts in the position shown in Fig. 1 of the drawings, is in mesh with the pinion 32, causing the same to rotate the drum 41 and Wind the cable 27 thereon to elevate the weight 25. The carriages 34 and 35 are maintained iu the position shown in Fig. 1 of the drawings by the eounterbalanceballs 38, which are adapted to move freelyin the cages formed by the body-rods 37 of the carriages. Vhen the float 7 has risen to such a height in. the casing 1 that the projection 21 has raised the Valve 2O to cause a discharge of the water in said casing through the siphon 18, the arm 8 and oat-ball 7 move downwardly, and the pawl 12, carried by said arm, passes inoperatively over the ratchet 11, which, together with the sprocket 10, is sustained against reverse movement by the spring-pawl 17. After the completion of sufficient chargings and dischargings of the casing 1 and consequent vertical oscillation of the arm 8, as above described, to raise the weight 25 to a predetermined height the latter engages the projection-piece 48 of the earriage 34 and tips said last-named carriage, as well as the carriage 35, to disengage the gear 45 from the pinion 32 and cause the engagement of the gear 41 with the pinion 32,which engagement is maintained by the counterbalanee-balls 38, which have then taken position at the otherend of the carriages. Wth the parts in the last-mentioned position the drum 29 is freed to turn under action ofthe weight 25 and cable 27 and by means of the pinions 32 turns the gear 41 and sprocket 42, which in turn operate the sprocket 43 to operate the pump 6 and raise a fresh supply of water through the pipe 5 to the reservoir or tank 3. Vhen the Weight 25 has fallen suiiiciently to engage with the lowermost projection 48, the carriages are again tilted until they assume the position shown in Fig. 1 of the drawings.

It will be understood from the above description that the work accomplished by the successive charges of waste water as the same rise in the casing 1 is conserved by the weight 25, which isv raised by the float 7, arm 8, drum 29, and intermediate parts. It is further evident that the rising Weight 25 automatically disconnects from the weight-lifting mechanism and connects with the pump-operating mechanism, thereby effecting the operation of the latter.

In Figs. 4 and 5 I have shown a modified form of the float mechanism hereinabove de- IOO IIO

IZO

for operating the valve 2O consists of the floatV 23 and connection 24. Secured to the free end of the iioat-rod 50, exteriorly of the casing, is a yoke 53, the ends of which are connected by a cross-head 54, with which is rigidly connected the free end of an arm 55, pivoted to a shaft 56 and provided with a pawl 12,-ratchet 11, and sprocket 10, which latter parts are arranged and operate the same as the corresponding parts shown in Fig. 1.

The operation ofthe modified constructionlast described is manifest from the foregoing description. lated by the rise and fall of the float 51 in the casing 49 and by means of the sprocket 10 causes the rotation of the drum 29, being in practice connected therewith in the same manner-as the corresponding parts in Fig. 1.

I do not desire to limit myself to the specic details of construction shown and described, but reserve the right to vary the same in adapting the apparatus to varying conditions of use without departing from the scope of my invention and the terms of the following claims.
